How Installing Energy-Efficient Windows in Antrim Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: In Antrim, you can lower your indirect greenhouse gas emissions by about 286 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Antrim
Windows come in various purposes, styles and shapes, so costs and services will differ tremendously based on several factors. Below, we detail the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. But costs will differ significantly based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Antrim homeowners $304+ each year after replacing single-pane windows.
Requesting free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first step when planning a window installation is to think about whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage. These installations are more involved and will increase the overall cost. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
Your window installation company will be able to recommend the best type for your project. In Antrim, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Antrim
In our hunt to make your home improvements easier and more eco-friendly in Antrim, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We’ve reviewed the best window replacement companies in Antrim primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Antrim, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Antrim.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, professionalism, warranty, quality of parts, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Antrim’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Antrim window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Antrim, PA Window Replacement FAQs
How much should a window install cost?
The national average cost to install a window is around $600 but can range from $200 to $1,200, depending on several factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
